AXLE-BOX.

SPECIFICATION forming part of Letters Patent No. 638,752, dated December12, 1899.

Application filed May 15, 1899. Serial 110.716,82?. (No model.)

To @ZZ whom it may concern:

Be it known that I, EDWARD ALFEIEND PERKINS, a citizen of the UnitedStates, residing at Gordon, in the county of Wilkinson and State ofGeorgia, have invented certain new and useful Improvements in Axle-Boxesand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to axles an d axle-boxes for vehicles, and has forits object the provision of certain improvements whereby the wear on theparts is minimized and equalized and the lubricant applied and retainedin a novel manner and the bearing parts protected from dust and otherforeign matter.

Having the foregoing and other objects in view, the invention consistsof certain improved features and novel arrangements and adaptations ofparts, as will appear more fully hereinafter.

In the accompanying drawings, Figure 1 is a view in side elevationembodying my inven tion, and Fig. 2 is a longitudinal section thereof. Y

The axle 1 has a tapering spindle 2, provided with an enlargedscrew-threaded portion 3 at its inner end. Over the spindle is iitted atapering sleeve 4, whose inner end screws on the portion 3, and it isprovided with an in ternal shoulder 5, which abuts the end of the saidthreaded portion. At the inner end of the sleeve is an enlarged portion6.

The numeral 7 designates a coupling fitted loosely on the eXtreme innerend of the sleeve 4 and having a shoulder 8 abutting the inner end ofsaid enlarged portion, thus preventing displacement of the coupling.Said coupling is provided with an integral nut-like portion 9 at itsinner end, which aifords a means for manipulating said coupling.

The numeral 10 represents the axle-box, the same being fitted in the hubof the wheel and of tapering form. It is adapted to turn on the sleeve 4and is provided with an internal enlargement where it is fitted looselyover the enlarged portion 6 of the sleeve, thus provid ing the internalshoulder 11, which abuts the outer end of said enlarged portion andlimits the inward longitudinal play of the box. The inner end of the boxis provided with screwthreads 12, engaging similar internal screwthreadson the coupling. The'outer end of the axle-box is closed, and it isprovided with an oil-feed opening 13, through which the lubricant can beapplied to the sleeve and interior of the box. This opening is closed bya removable Screw-threaded plug 14. A nut l5, screwed on the outer endof the boX, bears against the hub and holds it in position against thecoupling.

The numeral 16 designates a cup-shaped sand-band, which houses thenut-like projection on the coupling and bears against the latter. It isfitted snugly on the axle and is provided with a flat integral arm 17,held firmly by the usual clip on the axle. This band can be made inseparable halves instead of one piece, if preferred.

The outer end of the box being completely closed, it is rendereddust-proof and the lubricant can neither escape nor drip or becomeimpregnated with foreign material. At the other end of the bearing thesand-band excludes the dust, and thus the parts are absolutelyprotectedand smooth and easy running is insured.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

vl. The combination with an axle having a l screw-threaded portion, of asleeve iitted over the axle and engaging said screw-threaded portionwhich is provided with an enlarged portion intermediate its ends, acoupling having a bearing on the inner end of the sleeve and providedwith a shoulder abutting the inner end of the enlarged portion, a box,free to turn on the sleeve, which has its bore enlarged at its inner endwhich loosely receives the enlargement of the sleeve and providing ashoulder abutting the outer end of the enlarged portion aforesaid, saidbox having its inner end screwed into the coupling whereby longitudinalplay of the box and coupling is prevented.

2. The combination with an axle, 0f a sleeve fitted thereover which isscrewed onto the axle, a coupling having abearing on the sleeve and heldagainst displacement by the latter, and a box which receives the sleeveand is connected to the coupling, said box being closed at its Outer endand having a feed- Io opening for introducing the lubricant to itsinterior and a closing device fol` said opening. In testimony whereof Iax my signature in presence of two Witnesses.
